ART OF JOINING METAL-STRAP :ENDS.

Specification of Letters Intent.

Application filed April 16, 1911. :Serial No. 619,338.

Patented Sept. 10,19i2.

N To all whom it mag concern:

Be it known that I, ELLSWORTH E. .FLoRA, a. citizen of the United States, residing at -Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement in the Art of Joining Metal- Strap Ends, of which the following is a specification.

My object is to provide a novel, simple and effective Way of securely joining the ends of metal straps and especially such straps when employed as binders for boxes,-

bales and other packages,

In the accompanying draw1ng-F1gure 1 shows a box of the metal bound type, provided centrally with a surrounding metalstrap joined at its ends in accordance with my invention; Figs. 2, 3and 4, are enlarged fragmentary views showing, respectively, the outer side, edge and inner side of the joined strap-end sections; Fig. 5, an enlarged transverse section taken on line 111 Fig. 4; and Fig. 6, 1s a fragmentary v1ew illustrating how the strap may be addi-- tionally crimped to contract and tighten 1t;

around the box.

In joining together the ends of the metalstrap 7 when employed, for example, as a binder for a'box, the end-sections 8, 9 of the strap are drawn together and one brought into overlapping contact with the them to curl and meet, as indicated, to form substantially cylindrical interlocking crimps 10 in the sections. At the point where the straps are thus curled or crimped the outer section envelons the inner one, thereby joining them securely together. Thenatural effect of the crimping operation, as it is performed, is to kink and contract thestrap lengthwise, thereby tightening it around the box. While one crimping operation will secure the strap-ends together, additional interlocking crimps will add to the security of the fastening.

It is'desirable that the strap 7 shall tightly surround the box, and if'after the ends have been joined, as described, the strap is not sufiiciently tight, it may be additionally crimped along its length, as indicated at 11, to further contract it about the box or package. The crimping operation is so performed that the curled edges of the sections are on the under side, thus making it very diflicult, if not impossible, to insert a tool and open t-l-iefastening, which thus forms a particularly secure sealing means for the box or package.

What I claim as new and desire to secure by Letters Patent isr The improvement in the art of joining metal strips, which consists in overlapping the same and thereafter crimping them edgewise into infolding contact, thereby locking the parts against relative movement.
